Re: Emulating MT-32 on an RPi2

in MT-32 General
gdjacobs, i have gotten this up and running, but i sometimes get PCM recover, underrun errors upon exiting dosbox. So far, it hasn't been a deal breaker, but I suspect it coincides with game hangs and sound stutters I occasionally get. I set Munt to -m -i 25& to get a solid 25ms buffer (which is …

From what I have experienced, there was an intermediate time that Microsoft absolutely required an account of some kind, but they got a ton of backlash and reintroduced the offline account option. I setup about 15 laptops a year that I buy directly from Dell, and I went through a period of about 6 …

Re: VIDEO Patch for pixel-perfect scaling (SDL1)

By the way, can you perform aspect-ratio correction using the analog control on your CRT display that stretches or compresses the image in the vertical direction? Short answer is yes. Long answer is that there are no external controls to do so. I am quite used to opening up and repairing CRTs, but …

Applying the patch is as simple as calling patch -p0 < file.diff from the source root. Thank you. Interesting. Could it be because of the custom splash screen? That is very interesting. That actually might solve my whole problem. Since your screen is only 240x320, you don't need any scaling …

Re: DOSBox ECE (for Windows & Linux)

Posted on 2019-12-12, 22:06

That's doubtful. 320x240 is pretty low res for Xorg. I'm launching from the command line. No X desktop on my pi. I've never tried to run any dosbox from within X. EDIT: It has been suggested to me that the 640x480 resolution minimum could be a function of a "custom splashscreen" in ECE dosbox. Is …

I've never compiled ECE on raspberry. However the following works for me in debian x64. Thanks. I believe that this is essentially what I did. Problem is that it's crashing on startup because ECE seems to be demanding a minimum of 640*480 and I'm running a CGA monitor at 320*240. Regular dosbox …

Re: DOSBox ECE (for Windows & Linux)

The patch I'm referring to adds information to build a debian package from source. Thanks so much for the more detailed explanation. I will give this a shot tonight. I wonder if this will solve my issue in which dosbox ECE complains of no resolution of 640x480 available? (because I'm running this …

I am attempting to get pixel perfect scaling via dosbox on Raspberry Pi 4. I run it on a arcade monitor (CRT) at 240p via an analog connection. Regular dosbox runs as intended, but the scaling options yield poor results. Wondering if anyone here has any experience to apply this patch on a raspberry …

Re: DOSBox ECE (for Windows & Linux)

There's a way to build and run DOSBOX ECE on Raspberry Pi 4? Several ways. I usually use the build tools patch from the Debian source package. gdjacobs, could you elaborate a bit on the "build tools patch from the Debian source package? you can just patch vanilla to be ECE? is that by downloading a …

Re: DOSBox ECE (for Windows & Linux)

Been trying to get ECE running on my Raspberry Pi 4. Have been running the SVN build up until now with no serious issues, but I crave pixel-perfect because I'm playing on an arcade monitor (CRT). I successfully compiled version 4280 on raspbian buster, but I'm have an issue starting up. ECE is …

I use primarily Linux and implemented several workarounds for DOSBox SDL 1.2 issues in Boxtron (including workarounds for fullscreen issues). Can you share some more details about your setup? (what distro, what version of DOSBox, X11 or Wayland, etc)? I'm running it on a raspberry pi, on raspbian …

Thanks Dreamer. I'll give that a shot. However, my version of Dosbox won't run in fullscreen mode (it's a linux variety that can't do that for some reason I don't understand) but I can set the "windowed mode" to 640x480 resolution. Hopefully that's the same result. Yes! I love the midi music to Dark …

I'm having trouble understanding how Dosbox interacts with the resolution of the system it being run on. Example: My system is set to output at 640x480 and a 15kHz horizontal scanning rate to an arcade monitor. Program I am playing is Dark Forces, 320x200 VGA (320x400) What would I set the dosbox …
